Question on R4 size locking nut

[Econ]

I have a Fender HM strat neck that has an R4 size locking nut. Is the R4 size the biggest locking nut size in terms of width?

No, they make an R5 nut for guitars with a 1 3/4" nut width. An R4 nut is for a 1 11/16" nut width and it has wider string spacing than the R3 nut, which is also for guitars with 1 11/16" nut width.

+1 on all counts
